Feature Changes

RCM HA switchover on mass UP failure is now supported in 5G-UPF.

Previous Behavior: RCM HA switchover occurs instantly when all UPs go down.

New Behavior: RCM HA switchover occurs after three minutes when all UPs go down.

Customer Impact: Reloading all UPs will not trigger RCM HA switchover in the usual RCM operation as the operator intentionally reloads all UPs.

Note

Undetected network isolation is not likely in this case as L2 VRRP protocol will cover any such network isolation case.
